Answer:
Step-by-step explanation:
(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n
{Here -1 is distributed }
= <u>2n³ - n³</u> -<u> 3n⁴ + 8n</u>⁴ +<u> 7n + 7n</u>
{Combine like terms}
= n³ + 5n⁴ + 14n
Step-by-step explanation:
Using the given formula
I = P × R × t
I = 20 × 5/100 × 2
I = $2
8x^2+5x=-3
8x^2+5x+3=0
after solving this u will get x= (- 5(⁺ ⁻)√-71)/16
1/2 ÷ 1/2
= 1/2 ÷ 2/1
= 1/2 × 2/1
= 2/2
= 1
C.
The negative (-) means that you are losing 17 of something.
in I and II you are also losing 17 things. I you are losing 17 dollars and II you are losing 17 yards. III, however, you are gaining 17 degrees so it is not the answer.
